From 2093586de29418820b89aae05746511392f8ad73 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Wed, 12 Aug 2009 11:29:46 -0700 Subject: [PATCH] wimax/i2400m: USB driver uses a configurable endpoint map Newer generations of the i2400m USB WiMAX device use a different endpoint map; in order to make it easy to support it, we make the endpoint-to-function mapeable instead of static.
